Abstract

The present invention relates to a seal between the door and the windshield of a motor vehicle. This seal comprises a metal frame (1) extending along a post (M) of the vehicle body and having in cross section roughly the shape of a U, the base (2) of which is fixed to the upright (M), of which one (5) of the branches or wings carries an elastomer profile (6) with a lip (6a) applied to the edge of the windshield (P), and of which the other branch or wing ( 7) carries an elastomer profile (8) with a lip (8a) applied to the edge (B) of the door (O), the two elastomer profiles (6, 8) being connected by a membrane (9) and forming a unique piece obtained by extrusion on the frame (1). This seal can be shaped and attached to a body post of any passenger or utility vehicle.

Description

The present invention relates generally to seals

  sealing and more particularly relates to a seal between the door and

windshield of a motor vehicle.

  Seals have already been proposed which are capable of connecting a body of a vehicle body to a side edge of the windshield and to the edge.

  front neighbor of a vehicle door.

  Seals are thus known which comprise a metal reinforcement extending along the body frame and having in cross section roughly the shape of a U whose base is fixed to said upright, one of whose branches carries an elastomeric profile. with lip applied to the edge of the windshield and the other leg carrying a lip elastomer profile

applied on the edge of the door.

  However, these known seals have a certain number of drawbacks among which must be mentioned the difficulty and the cost of manufacture, as well as the complexity of the structure and appearance of the seal, due to the fact that said seal must in reality be consisting of several separate joints to be able to

  correctly fill in the various sealing functions with respect to the

breeze and vehicle door.

  The present invention is intended in particular to overcome the above disadvantages by providing a seal easy to manufacture, inexpensive, a unitary structure, easy to mount on the body amount, and

  a clean appearance to be confused with the profile of the body.

  For this purpose, the subject of the invention is a seal connecting a body of a vehicle body to a side edge of the windscreen and to the front edge adjacent to a vehicle door, and of the type comprising a metal frame extending along the upright and having in cross section roughly the shape of a U whose base is fixed to the upright, one of the branches or first branch carries a lip elastomer profile applied to the edge of the windshield and whose other branch or second branch carries a lip elastomer profile applied to the edge of the door, characterized in that the two elastomer profiles form a single piece obtained by

extrusion on the frame.

  This joint is further characterized in that the two profiles are connected by a membrane covering the armature, while the second leg of the U removably receives the corresponding elastomeric profile which presents

a form of clamp.

  According to a preferred embodiment, the above-mentioned profile in the form of a clamp clings to the second branch of the U which is either bare or coated.

  elastomer as the whole frame.

  According to yet another characteristic of this seal, the elastomeric profile carried by the first branch of the U comprises a second lip

  applied on the front edge of the door.

  But other features and advantages of the invention will appear

  better in the detailed description which follows and refers to the appended drawings,

  given only by way of example, and in which: Figure 1 is a partial view in perspective of a vehicle and illustrates the part of the vehicle with the windshield; Figure 2 is an enlarged sectional view along the line II-II of Figure 1; Figure 3 is a view of the seal illustrated in Figure 2, but shown here isolated, that is to say not fixed on the amount of the vehicle body; and FIGS. 4 and 5 respectively illustrate two variant embodiments

of this seal.

  A seal according to this invention is intended to connect an amount M of bay or body of a motor vehicle to a side edge of the windshield P and to the front edge neighbor B of a door O of the vehicle, as this is good

visible in Figures 1 and 2.

  According to the embodiment visible in FIGS. 2 and 3, the seal according to this invention comprises a metal frame of aluminum or the like 1 extending along the upright M and having in cross section roughly the shape of a U whose base 2 is fixed to the amount M by means for example of screws 3 and staples 4, as can be seen in FIG. 2, it being understood that any method of attachment other than that shown may

  perfectly be used without departing from the scope of the invention.

  The U of the frame 1 comprises wings or branches, namely on the one hand a first branch 5 carrying an elastomer profile 6 with a lip 6 applied on the edge of the windshield P, and another lip 6b which can be applied on the front edge B of the door O, as is clearly visible in FIG. 2, and on the other hand, a second wing or branch 7 also carrying an elastomer section 8 with a lip 8 capable of apply on the front edge B of the

door O of the vehicle.

  According to an essential characteristic of the invention, the two elastomer profiles 6 and 8 with their associated lips 6a, 6b and 8a form a piece

  unique made by extrusion on the frame 1.

  As it is clear from FIGS. 2 and 3, as well as from FIG. 4 illustrating another embodiment of a gasket according to this invention, the two sections 6 and 8 are connected by a membrane 9 covering in a way frame 1 and forming with it a gutter or

a channel 10.

  In the embodiment illustrated in FIGS. 2 and 3 on the one hand, and in FIG. 4 on the other hand, the second wing or branch 7 of the U of the armature 1 removably receives the elastomer section 8 conformed to the In this way, as can be understood from FIGS. 2 and 3, the clamp 11 can be hooked on the armature leg 7 of the armature so as to close the gutter 10 and conceal the fixation. 3, 4 Nevertheless, in order to gain access to this fastener for mounting or dismounting the armature, the clamp 11 may

  be easily extracted from branch 7.

  In the embodiment of FIGS. 2 and 3, the branch 7 is coated with elastomer as is the base 2 of the armature which, finally, is

  completely coated with elastomeric material.

  In the variant of Figure 4, the branch 7 is bare, that is to say is not

  coated with elastomeric material, as well as the base 2 of the U of the armature.

  Thus, in the embodiment of Figures 2 and 3, the clamp 11 may be extruded in the open position, or, in the case of the embodiment of Figure 4, the branch 7 may not receive a primer, it that is to say of product impregnating the frame before extrusion to cause the adhesion of the elastomer. The variant visible in FIG. 5 is simpler than the previous ones, in the sense that here the entire reinforcement 1 is of course coated with elastomeric material, but no membrane is provided such that the two elastomer profiles are joined together. 6 and 8, and the elastomeric profile 8 does not form a detachable clip of

  the armature 1 since it is integral to said armature coming from extrusion on it.

  In all the seal variants described above, the seal according to this invention forms a single piece in that the elastomer profiles are extruded with the metal frame to form a set which is subsequently bent and curved to follow the shapes of the vehicle body and thus integrate in itself functions of lateral finish of the windshield P, of an antifouling side of said windshield, sealing with the door of the vehicle (lips 6b, 8a), and also cover-fixing (membrane 9). Therefore, the advantages of such a seal will be numerous and in this respect we can mention a price gain due to the integration of functions, a beautiful aspect of the outside due to fewer parts and berthing, and a bigger

  Accurate seal-windshield and door seal

  Of course, the invention is not limited to the described and illustrated embodiments which have been given only by way of example. Thus, the shape of the lips belonging to the two elastomer profiles can be any and appropriate. depending on the body of the vehicle to be equipped.
